Definitions
- This invention relates to circuit breakers, and, more particularly, to a rotary contact assembly for high ampere-rated circuit breakers.
- U.S. Patent No. 4,616,198 entitled Contact Arrangement For A Current Limiting Circuit Breaker describes the early use of a first and second pair of circuit breaker contacts arranged in series to substantially reduce the amount of current let-through upon the occurrence of an overcurrent condition. A more recent description is found within U.S. Patent Application Serial No. 09/087,038 filed May 29, 1998 entitled Rotary Contact Assembly For High Ampere-Rated Circuit Breakers.
- vacuum circuit interrupters wherein continuous wiping of the contact surfaces is imperative to long term operation, the wiping motion is achieved by the addition of a wiping spring in addition to the contact closing springs for continued motion of the contacts in the parallel plane after the closing springs have initially become engaged.
- a wiping spring used within vacuum circuit breakers is found in Canadian Patent No. CA 1,098,570 entitled Contact Controller For Vacuum-Type Circuit Interrupter.
- EP-A-0 889 498 discloses a circuit breaker moveable contact assembly according to the preamble of claim 1 and 9.
- the circuit breaker rotary contact assembly employs a common pivot between the rotor assembly and the rotary contact arm.
- a pair of off-center expansion springs directly engage the rotor at one end and engage the rotary contact arm via a linkage arrangement at an opposite end thereof.
- Separate pivots are provided to the rotor assembly and the moveable contact arms ensure that the contacts close prior to complete rotation of the rotor assembly. The additional rotation force provided by the rotor assembly then translates into lateral displacement of the moveable contacts relative to the fixed contacts, resulting in contact wiping function.
- An alternate embodiment utilizes a common pivot point between the rotor assembly and the moveable contact arms, while providing slight post closure motion by means of a fixed contact support spring.
- the circuit breaker rotary contact assembly 10 shown in Figure 1 is similar to that described within the aforementioned U.S. Patent No. 4,649,247 and the aforementioned U.S. Patent Application Serial No. 09/087,038 filed May 29, 1998 entitled Rotary Contact Assembly For High Ampere-Rated Circuit Breakers, both of which are incorporated herein by reference.
- Opposing line and load straps 11, 12 are adapted for connection with an associated electrical distribution system and a protected electric circuit, respectively.
- Fixed contacts 24, 26 connect with the line and the load straps while the moveable contacts 23, 25 are attached to the ends of moveable contact arms 21, 22 for making moveable connection with the associated fixed contacts to complete the circuit connection with the line and load straps 11, 12.
- the movable contact arms 21, 22 are of unitary structure and rotate within the rotor and contact arm assembly 15 about the contact arm pivot 27 when rotated upon response to the circuit breaker operating mechanism (not shown) by connection via the pins 18 and the pair of opposing levers 16, 17.
- the arcs generated when the contacts 23, 24 and 25, 26 are separated upon overload circuit current conditions are cooled and quenched within the arc chambers 13, 14 to interrupt current through the protected circuit.
- the rotor 19 rotates about a rotor pivot 20 in response to the circuit breaker operating mechanism and interacts with the moveable contact arms 21, 22 in the manner best seen by now referring to Figure 2.
- the contact assembly 15 in the circuit breaker rotary contact assembly 10 of Figure 1 is shown in Figure 2 as a rotor 19 in the form of a pair of opposing rotors, with only one of which depicted for purpose of clarity.
- the opposing rotors 19 are connected with the moveable contact arms 21, 22 by means of pins 29 extending within slots 28 formed within opposing sides of the rotors.
- Compression springs 30 extend between the pins 28 to allow simultaneous rotation of the rotors and the movable contact arms about the rotor pivot 20 and the contact arm pivot 27.
- the rotor pivot 20 is off-set from the contact arm pivot 27 by a predetermined distance "d" and the fixed contacts 24 are longer than the moveable contacts 23 by a predetermined distance "x” to provide automatic contact wiping between the movable contacts 23, 25 and fixed contacts 24, 26.
- the rotor 19 rotates in common with the moveable contact arm pivot 27 and the rotor is attached to the moveable contact arm pivot by the arrangement of pins 29 within slots 28 and by means of expansion springs 30, in the manner described earlier.
- the moveable contacts 23, 25 are smaller than the fixed contacts 24, 26 to the same extent as described earlier herein.
- the fixed contacts are arranged within a fixed contact receptacle 31, that includes a compression spring 32.
